thank you, i kinda figured that was about right yet wanted to consult the
wisdom on the list...
also, there is another place that allows one to change the sectors per track
size for "maximum boot size".... choices are 32 sectors per track or 63
sectors per track on this compaq dl380 with 4 18.2 gig 10k scsi drives in
array.
i get the idea in terms of a simple ide workstation yet i have not the
practical experience with this specific machine with scsi and raid5 config.
suggestions please?
thanks!
